Clinical prevention in nursing is about actions taken with patients and their families to keep people healthy and reduce the chance of illness or complications. The statement that best fits this is health promotion and risk reduction/illness prevention for individuals and families because it centers on the care provided at the bedside or in routine care, aiming to prevent disease before it starts or detect it early through personalized guidance, vaccines, screenings, and lifestyle counseling tailored to the person and their family context.

The other options describe broader public health or treatment activities rather than the patient-and-family–focused preventive work. Population-wide environmental policy development is about policies that affect communities rather than individual care. Treatment of established disease in hospital settings is about curative or management efforts after illness has already occurred. Genetic screening of entire populations implies large-scale screening at a population level, not the individualized, family-centered prevention emphasized by AACN.
